Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Because the common bandwidth according to actual needs of the high-speed interface number in Eia interface, Eib interface or the Eic interface is determined, is the example explanation to have general a plurality of high-speed interface numbers earlier at this.
According to the influence degree of data that each high-speed interface transmits to the normal operation in base station, the data priority of district office's transmission.Usually, because the data of the Iub interface between base station and the base station controller comprise chain of command and user face data between base station controller and the base station, as highest priority data, descending cell data takes second place, the uplink cells data are taken second place again, and other data based its importance are determined its priority orders.Because the data format difference of various data, the priority of data can be distinguished by analyzing packet.
Embodiment 1: following to comprise in Eia interface or the Eib interface that three high-speed interfaces are that example is illustrated.
Referring to shown in Figure 3, the data of up 1～6 sub-district of high-speed interface 1 transmission and the data of the Iub interface between base station and the base station controller, the data of descending 1～6 sub-district of high-speed interface 2 transmission, the data of up 7～12 sub-districts of high-speed interface 3 transmission.
If high-speed interface 1 is unusual, Iub transmission data can't arrive another piece BBU; If be equipped with or can not arrive main BBU from BBU transmission data, then cause the Iub port band width to reduce in addition the base station unavailable; If high-speed interface 2 is unusual, all downstream signals can't pass to another BBU, cause part cell downlink no signal; If high-speed interface 3 is unusual, cause reducing of up-link capacity.For overcoming the problems referred to above, BBU determines the data priority that each high-speed interface transmits by analyzing data format, that is: the data transmitted of high-speed interface 1 have limit priority; Because will the causing unusually of high-speed interface 2 can not be shared downlink data between the BBU, may cause the unavailable of part sub-district, so the data that high-speed interface 2 is transmitted have inferior high priority; The data that high-speed interface 3 is transmitted have lowest priority.
Referring to shown in Figure 4, Fig. 4 a to Fig. 4 g shows the method that each high-speed interface is switched when unusual.Be specially:
As Fig. 4 a, at three road high-speed interface states just often, the three tunnel transmit up 1～6 cell data and Iub interface data, descending 1～6 cell data, up 7～12 cell datas respectively.
As Fig. 4 b, when high-speed interface 1 is unusual, take high-speed interface 3 up 1～6 cell data of transmission and Iub interface data, obtain the stable of Iub interface with the method that reduces up-link capacity, guarantee the operate as normal of base station.
As Fig. 4 c, when high-speed interface 2 is unusual, take descending 1～6 cell data of high-speed interface 3 transmission, obtain the correct of down going channel with the method that reduces up-link capacity.
As Fig. 4 d, high-speed interface 3 does not deal with when unusual, because of the data priority of this interface transmission is minimum, only can influence up-link capacity.
As Fig. 4 e, high-speed interface 1 and 2 takies high-speed interface 3 up 1～6 cell data of transmission and Iub interface data when unusual, guarantees the operate as normal of the stable and base station of Iub interface.So only can have influence on sharing of part upstream data and downlink data, reduce the up-downgoing capacity.
As Fig. 4 f, high-speed interface 1 and 3 takies high-speed interface 2 up 1～6 cell datas of transmission and Iub transmission data when unusual, guarantees the operate as normal of the stable and base station of Iub interface.
As Fig. 4 g, high-speed interface 2 and 3 does not deal with when unusual.
Embodiment 2: following to comprise in Eia interface or the Eib interface that 5 high-speed interfaces are that example is illustrated.
